Finding a real wholesaler for console systems and new games is very hard. And When one comes along they are bought out very quickly by people in that market with plenty of money to buy stock.
Most of the big boys buy them directly from the manufactures in pallet lots of 200 Units and the wholesale price is not very much lower then the retail value. I would suggest that if you are not in this field and established that you dont attempt to try. Many have lost thousands to scammers in this area.
